Union
Example;
Set a = {1, 2, 3}
Set b = {4, 5, 6}
The answer is A ∪ B = {1, 2, 3, 4, 5, 6} so basically if union you combine the elements of the set, take note that you can only put the number once.
Intersection
Example
Set a = {2, 5, 6, 10, 11}
Set b = {4, 5, 6, 12, 14}
The answer is A ∩ B = {5, 6} if intersection the answer is the commmon/same elements from the sets.
Difference
The answer is A - B = {2, 10, 11} in difference set, you subtract the same elements, this set is opposite of the intersection.
Some more examples for difference sets.
Set C = {2, 5, 11, 35, 37}
Set H = {5, 10, 35, 36, 37}
The answer is C - H = {2, 11} I removed the 5, 35, and 37 since those elements are on set H, hope u understand
